In this section, we aim to design an advanced DRL algorithm to solve the resource management problem in () in a stationary environment. Since each V2I link is preassigned a sub-band with the fixed transmit power, we focus on solving the sub-band assignment and the power allocation for V2V links. DRL is an important branch of machine learning methods, which uses deep neural network (DNN) to enhance the learning efficiency of reinforcement learning (RL) [1]}. Full details of the proposed algorithm are presented below.
